VALVE.

Specification of Letters Patent.

Application filed March 25, 1916. Serial No. 86,731.

The invention is particularly directed toA a valve which is adapted foruse in connection with pneumatic mattresses or similar devices, thevalve being used for iniiating the mattress.

According to this invention a valve casing -pis provided which ispreferably adapted to screw into a bushing or similar part carried bythe mattress, vmeans being provided for making a tight joint therewith.The valve casing is also provided with a screw-threaded outer end ornipple designed to make connection with an ordinary inliatino or with ,aap for closing the end or the cas- 4ing, and inwardly of said nipple isprovided a shoulder for receiving the end of an ordinary rubber tube,which may be used `for Vin flating purposes in lieu of the pump.

Referring to the drawings which illustrate one form of the invention,-

Figure l is an elevationof a complete valve, the bushing being shown insection.

Fig-2 is a diametrical section of Fig.. l

-on a larger scale.

- Fig. 8 is a plan view of Fig. 2. .Referring to the drawings, let Aindicate I the wall of a pneumatic mattress, pillow, or

other similar device which it is desired to inflate, B is a bushinghaving a iiange C adapted to lit on one side of the wall of the mattressand D is a nut which may screw von the inner side fof the bushing toclamp the wall of the mattress against the flange C.

Packings may be introduced between the flanges and mattress wall ifdesired. The bushing B has a screw-threaded aperture E which is designedto receive the valve F.

The valve F, as best shown in Fig. 2, is constructed with a casing G,the lower part of which is provided with a flange H, preferably ofconsiderable size, which flange per- 'forms the double purpose of actingas a backing or bearing face for the packing l, and also acting as amanipulating iange. Below the flange H is a screw-threaded part J whichis adapted to screw in the bushing B until the packing l is compressedagainst the' top of the bushing.

Any suitable form of check member or valve proper may be used, thatshown being the well-known Schrader valve inside. The general torni ofthe casing G is cylindrical, and it is provided with a bore L whichleads completely through the easing, the upper part of the bore beingscrewthreaded, as shown. at M, to receive the valve mechanism. Theexterior of the valve casing at its upper end is also screw-threaded atO to receive a pump coupling, by means or' which air from the pump isied to the valve; it is also adapted to receive a valve cap or othersuitable closure for the end of the casing. `For these purposes theouter end of the valve casing constitutes a seat against which thepacking of the coupling or cap is compressed to make a tight joint.

Below the screw-threaded portion O l form a flange or shoulder P whichis adapted to receive a rubber tube., the function of the ilange beingto stretc the tube so as to make a leali-tight joint oetween' the tubeand the valve casing and also to prevent its accidental removal. Forthese purposes the shoulder P is preferably made with a curved ortapered Q on its upper side and a shoulder il on its lower side, thetapered face being adapted to guide the tube over the shoulder and theshoulder R being adapted to present a more or less abrupt tace tofrictionally engage the tube so that it cannot be accidentally.displaced4 By this means the ordinary hose may be used directly on thevalve or by mea-ns of a pump coupling, as may be most convenient.

VlVhile l have shown and described one form ci' the invention, it willbe understood that I do not wish to be limited thereto, since variouschanges may be made therein without departing from the invention.

YWhat l claim ist l. A casing for a valve or the like, having an outerend forming a scat, a screw-threaded portion adapted to receive a pumpcoupling and inwardly of said screw-threaded portion an externalshoulder adapted to receive a tube, said shoulder being of largerdiameter than the threaded portion.

2. A casing for a valve or the like, having means for engagement with adevice to be inflated, a screw-threaded outer-end, a seat at such endand an intermediate shoulder adapted to receive a tube, said shoulderbeing of larger diameter than the threaded portion.

3. A casing for a valve or the like, having means for engagement with adevice to be inflated, a screw-threaded outerend, a seat at such end andan intermediate shoulder adapted to engage a tube, and said shoulderhaving a tapered outer face.

4. A casing for a Valve or the like, having means for engagement With adevice to be inflated, a screw-threaded outer end, a seat at such end,an intermediate shoulder adapted to engage a tube, and said shoulderliav'v ing a tapered outer face, and an abrupt face beneath said taperedouter face.

5. A valve for mattresses or the like, comprising a casing having alower flange, a screw-threaded portion below said ilan'ge, a packinresting against saidiiange on its under si e, a Valve mechanism withinSaid casing, and said casing havin a screwthreaded outer end, a seat atsuc end and a shoulder between said liange and said outer end forengaging a tube, said shoulder being of larger diameter than thethreaded portion.

In witness whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses.
